Problem- What is the importance of the node found in the anti-bonding molecular orbital to the molecular bonding in H2?
A) It increases the strength of the molecular bond because is shields the repulsive force between the two positive nuclei.
B) It destabilizes the molecular bond because the electron cannot be located at the location of the node.
C) The electron cannot be located at the node, thus it isolates the electron to one of the two nuclei.
D) It is purely a mathematical artifact, so it has no effect on the molecular bonding.
